APPARATUS FOR USE IN CONNECTION WITH NAPPlNG-MACHINES.

SPECIFICATION forming part of Letters Patent No. 633,664, dated September 26, 1899.

Application filed June 17,1899. Serial No. 720,900. (No model.)

To all whom it may concern:

Be it known that I, Louis SCHNEIDER, a subject of the King of Saxony, and a resident of Mittweida, in the Kingdom of Saxony, German Empire, have invented a new and useful Improvement in Apparatus Suitable for Use in Connection with Napping or Teazeling Machines, of which the following is a specification.

The selvages of woolen cloth consist very often, as is well known, of material other than the body of the cloth itself, and in the manufacture and finishing of the cloth assume a Wavy form. It is often also thicker than the body of the cloth to be napped. hen the cloth comes to be napped or teazeled in a napping or teaz'eling machine, the action of the wire cards or natural teazels of the machine on the somewhat prominent portions of the wavy selvages, which are generally thicker than the body of the cloth,is so marked that the selvages are too much teazeled and often entirely or partly denuded of nap. The edges of the cloth are in each case rendered unsightlyand bare and difliculties are caused in its further finishing-for instance, in the stretching out or mounting by the selvages.

My apparatus according to this invention is intended to be applied to a napping or teazeling machine and to raise the'wavy selvages of the cloth at or near the place where the wire cards or teazels act upon the cloth, so thatthe selvages will be preserved from excessive napping or teazeling.

In the accompanying drawings I have shown one form of apparatus in which my invention is embodied.

Figure 1 thereof is a side elevation of the drum of a teazeling apparatus with my in? vention applied thereto. Fig. 2 is a plan view of the apparatus embodying my invention, on a larger scale. Fig. 3 is a side view thereof. Fig. at is an end view thereof, and Fig. 5 is a detail of a modification which will be hereinafter described.

Fig. 1 of the accompanying drawings shows at a the drum of a napping or teazeling machine, which is furnished at its periphery with rollers covered with wire cards or with nat ural teazels b b Z) Z).

(Z are the guide-rolls and c the. feed-rolls, which cause the cloth to travel in a course from w to a: and present it to the periphery of the drum a. This arrangement and its repe tition about the periphery of the drum are well known.

The apparatus is shown on a larger scale in plan in Fig. 2, in side View in Fig. 3, and in end View in Fig. 4:. It comprises a rod 2, which extends across the drum and is fur nished at each end with a comparatively thin cross-piece f, standing in a plane at right an gles thereto and bent around or hooked at both ends g g. The cross-pieces f rest on the guide rolls d (Z with their hooked ends g g embracing the latter, and can shift sidewise i. a, in a direction parallel to the axes of the guide-rolls. In order that the position of the end pieces may be adjusted exactly to the width of the cloth, the rod 6 is telescopic, so that it can be lengthened or shortened. The set-screw h serves to keep it at the required effective length. Instead, however, of this set-screw arrangement a helical spring 21, Fig. 5, adapted by its tension always to hold the end pieces f against the edges of the cloth, may be provided at each end of the rod 6.

On each end piece f there is an angular shield 70, which has at its lower part a project-ing finger Z, which at its lower end has a piece 0, adapted to project (at right angles thereto and parallel to the axis of the carddrum) under the selvage. This shield 7i; can be slid along the end piece fand held in the desired position by a set-screw m,which passes through a slot in the shield 7c and engages the end piecef. On the end piecef there is a finger n, which prevents the selvage from turning under,which otherwise might happen.

The shield 7;, with its finger l, is preferably placed not at the place 19*, Fig. l, where the carding or teazeling is effected, but so that the cloth will pass over its finger a little before reaching that place, as if it were placed at b the raising of the selvage by the horizontal part 0 of the fingerl would also remove a part of the body of the cloth itself from the desired action of the wire cards or teazels. The selvage, which is a little longer than the body of the cloth, is therefore raised by the linger before the cloth reached the place where it is napped or teazeled just enough to prevent undesirable action on the selvage of the cards or teazels.

Since the two end piecesfare adjusted to the edges of the cloth, the entire apparatus will follow any sidewise motion of the cloth which may ensue during the course of the latter through the napping or teazeling machine, so that even in case of such sidewise motion the selvage will be properly raised away from the action of the napping or teazeling rollers.

The effect of this apparatus is a marked improvement in the appearance of the cloth that is mapped or teazeled in the machine, because the wavy selvages are in no Way roughened or otherwise unfavorably affected by the cards or teazels.

I claim 1. Apparatus for napping or teazeling machines for preventing the injurious effect of wire cards or natural teazels on the selvages of cloth, said apparatus consisting of a crossrod a, capable of being adjusted to Width of cloth, said rod being provided at each end with parallel guides f g, each guide carrying an angular shield 70 with projecting finger Z having a horizontal part 0, to take under- 25 cards or natural teazels, the combination of 30 a cross-rod e, guides f g at both ends thereof, shields 7t carried by the said guides and provided with projecting fingers Z 0, the said guides being curved at their ends and guiderolls (1 loosely supporting the said guides so 3 5 as to permit the same to have a free movement sidewise thereon.

In testimony that I claim the foregoing as my invention I have signed my name, in presence of two witnesses, this 31st day of May, 40

LOUIS SCHNEIDER.
